Quizplus · Accepted Answer

Respiratory bronchioles divide to form multiple alveolar ducts, which further divide into alveolar sacs where gas exchange takes place. Secondary and tertiary bronchioles lead to respiratory bronchioles, while terminal bronchioles lead to respiratory bronchioles or alveolar ducts. Alveolar sacs are not a part of the bronchial tree but are located at the end of the alveolar ducts.
